Form shortcuts

[lkleuver]

Moved focus shortcuts to Form component to handle both submit and focus events.

Closes #207

This PR solves ENTER from last input field moves focus to submit button. from #207 but not SHIFT + UP arrow: navigate to first input on page (the first candidate) is this indeed intended?

Missing the added hint (shift + down arrow) in the bottom bar.

• Copy of that hint differs for lists and other form sections.
• The hint should appear below the 'accept warnings' checkbox if that is shown.

(you can leave out the 'spacebar' hint untill that is implemented in #207)

I could fully implement #207 perhaps excluding the spacebar search?
shift up is a small change

Does it (design wise) make sense to add the Shift+↓ shortcut on the Voters and Votes and Differences pages? I'd say they are only useful on the political group votes pages.

That's a fair point. We could leave out the hint / description at the bottom of the page. Not sure we should leave out the entire shortcut. Prefer consistent behavior over all our forms.

Retested, works as expected now!
